Minimizing Hyperbolic Embedding Distortion with LLM-Guided Hierarchy Restructuring

Melika Ayoughi, Pascal Mettes, Paul Groth

Hyperbolic geometry is an effective geometry for embedding hierarchical data structures. Hyperbolic learning has therefore become increasingly prominent in machine learning applica…

Balanced Hyperbolic Embeddings Are Natural Out-of-Distribution Detectors

Tejaswi Kasarla, Max van Spengler, Pascal Mettes

Out-of-distribution recognition forms an important and well-studied problem in deep learning, with the goal to filter out samples that do not belong to the distribution on which a…

How PARTs assemble into wholes: Learning the relative composition of images

Melika Ayoughi, Samira Abnar, Chen Huang +10

The composition of objects and their parts, along with object-object positional relationships, provides a rich source of information for representation learning. Hence, spatial-awa…

Self-Contained Entity Discovery from Captioned Videos

Melika Ayoughi, Pascal Mettes, Paul Groth

This paper introduces the task of visual named entity discovery in videos without the need for task-specific supervision or task-specific external knowledge sources. Assigning spec…
